@rozo, Hi I've ben considering building my own ETH mining rig after watching your DIY videos on youtube, just curious to know a) if there is any way of telling how long the GPU or the mining rig would mine profitably until the hash rate requires upgrading to higher hash rate and b) how long do the components in this rig last (avoid breakdown/failure) especially they they are running 24/7 for 365 days. Would appreciate your advice :)
